Cpanel using Exim as MTA

Hi, after searching for my reply for a day atlast I am confirmed that Cpanel use only exim, Its simple that I can ask them , but believe me I have a post in their forum that doesn't have reply until one day past :( And now I am able to install exim on my PC. A Bit different from other softwares that I install on linux box from source. Actually I miss "configure" file for it... But at the end I read its README and all is done as a piece of cake So In future , do read README or INSTALL or such files before doing something new. Best of luck all Sumit Gupta
